IN THESE CONDITIONS While most of us where huddled inside trying to escape the cold today. One Johnston man actually could not wait to get outside. KCCI's Laura Nichols introduces us to a runner who thinks NO temperature is too cold to train for your dreams. Look around Central Iowa streets on a day THIS cold... and you won't find a soul... But head into one Johnston neighborhood ... and the sound of running footsteps will make you do a double take... To Mark Cooper -- the negative degree wind chills are no big deal... ONCE YOU WARM UP IT'S NO DIFFERENT THAN ANY OTHER DAY. SOME PEOPLE MIGHT SAY YOU'RE CRAZY! YEP, LOTS OF PEOPLE SAY THAT. Maybe not crazy ...but determined. The research scientist, who's originally from Scotland, is training for one of the toughest challenges of his life...a marathon at the North Pole ... THE NORTH POLE IS GOING TO BE A LOT COLDER THAN THIS SO IF I COULDN'T HANDLE THIS I MIGHT AS WELL CANCEL MY TRIP. So while everyone else barely left their house Monday...Mark got up at 5am to hit the pavement ... HE CAME THROUGH TO WAKE ME UP, AND I GOT A SHOCK. I WAS LIKE YOUR FACE IS LITERALLY FROZEN. I WORRY THAT SOMEONE MIGHT NOT SEE HIM ON THE ROAD OR THAT HE'LL FALL AND FREEZE TO DEATH. BUT SO FAR SO GOOD. At 50 years old ...MArk has already done 12 marathons all over the world. I ACTUALLY CAN SPEND A LOT OF TIME LOOKING AND LEARNING WHEN I'M RUNNING, AND SO IT WAS JUST AN OPPORTUNITY TO GO BACK AND TAKE THE SIGHTS IN. His love for travel and for running ...is what keeps him going. MAKES YOU REALIZE THAT ANYTHING IS POSISBLE WHEN YOU PUT YOUR MIND TO IT. I'M CONVINCED ANYONE COULD DO IT IF THEY PUT THEIR MIND TO IT. THE ONLY DIFFICULT PART IS CONVINCING YOURSELF THAT YOU WANT TO MAKE THE COMMITMENT.. The average temperature is about negative 35 degrees in the North Pole. Not to mention Cooper will be running through knee high snow ... But he says he can't wait to finish his 13th marathon
